A zebrad application component that manages the active collection, reception, gossip, verification, in-memory storage, eviction, and rejection of unmined Zcash transactions (those that have not been confirmed in a mined block on the blockchain).
Major parts of the mempool include:
- Mempool Service
- runs in the background to periodically poll peers for fresh unmined transactions
- Queue Checker
- runs in the background, polling the mempool to store newly verified transactions
- Transaction Gossip Task
- runs in the background and gossips newly added mempool transactions to peers
User-configurable mempool parameters.
